Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Referring to fig. 1 to 5, a dust removing box 100 according to an embodiment of the present invention includes a box body 10, the box body 10 has an air inlet 101 and an air outlet 102, an airflow carrying garbage is adapted to enter the box body 10 from the air inlet 101, and then the garbage in the airflow carrying garbage is collected into the box body 10 (or a garbage box a connected to the box body 10) through operations of filtering, garbage and airflow separation, etc. in the box body 10, and the airflow after dust removal will be sent out from the air outlet 102.

In order to facilitate the filtering of the airflow carrying the garbage, the invention is provided with the filter screen assembly 22 for preliminary filtering of the airflow carrying the garbage so as to filter out larger-volume impurities and have certain filtering effect on some fine dust and the like. The dust removing box 100 of the present invention may further include a turnover mechanism 20, wherein the turnover mechanism 20 includes a rotation shaft assembly 21 and a plurality of screen assemblies 22, the rotation shaft assembly 21 is connected to the box body 10, and the plurality of screen assemblies 22 are connected to the rotation shaft assembly 21 and are arranged around the rotation shaft assembly 21 at intervals in the circumferential direction. At least one of the plurality of screen assemblies 22 shields the air duct between the air inlet 101 and the air outlet 102, and the turnover mechanism 20 can rotate around the axis of the rotating shaft assembly 21 along the airflow direction to switch the circumferential positions of the plurality of screen assemblies 22, wherein the airflow direction is the flowing direction of the airflow when the airflow flows from the air inlet 101 to the air outlet 102. In the using process, at least one of the plurality of filter screen assemblies 22 is shielded in the air duct between the air inlet 101 and the air outlet 102, the air flow which is introduced from the air inlet 101 and carries the garbage can be filtered, and the filtered air flow is led to the air outlet, in addition, the turnover mechanism 20 can rotate, so that the positions of the plurality of filter screen assemblies 22 can be adjusted, therefore, when one filter screen assembly 22 is blocked, the positions of the plurality of filter screen assemblies 22 can be adjusted through the turnover mechanism 20, the switching of the filter screen assemblies 22 is carried out, and the service life of the dust removal box 100 is prolonged.

According to the dust removing box 100 provided by the embodiment of the invention, the plurality of filter screen assemblies 22 are arranged, and the position adjustment of the plurality of filter screen assemblies 22 is realized by rotating the turnover mechanism 20, so that the blockage is avoided, and the service life of the dust removing box 100 is prolonged.

The dust removing box 100 may further include a filter element disposed downstream of the turnover mechanism 20 and adapted to further filter the airflow to the air vent, wherein the filter element is a flexible filter element 30, which may be a cloth bag or the like, as described below. In addition, the turnover mechanism 20 of the present invention can automatically turn over under the driving action of the air flow, and can also be driven to turn over by using other driving structures. For example, when the filter screen assembly 22 filters the airflow carrying the garbage, the attached impurities on the filter screen assembly 22 gradually increase along with the filtering process, and when the attached impurities on the filter screen assembly 22 increase to a certain degree, the wind resistance of the filter screen assembly 22 increases, and at this time, the thrust of the airflow to the filter screen assembly 22 also increases, so as to prompt the turnover mechanism 20 to automatically turn over, thereby realizing the position switching of the plurality of filter screen assemblies 22. For another example, a driving mechanism such as a motor may be connected to the turnover mechanism 20, and the turnover mechanism 20 may be rotated by the motor to switch the positions of the plurality of screen assemblies 22.

Wherein, when the turning mechanism 20 is driven to rotate by wind, a certain damping can be provided to the turning mechanism 20 so as to limit the rotation of the turning mechanism 20, but the turning mechanism 20 is driven to turn when the thrust of the airflow to the filter screen assembly 22 reaches a certain degree. That is, a damping member for limiting the turnover of the turnover mechanism 20 is provided between the turnover mechanism 20 and the tank body 10. In combination with the following, the ash vibrating mechanism 40 is arranged in the invention, and the ash vibrating mechanism 40 is arranged to be in transmission connection with the turnover mechanism 20, at this time, the turnover mechanism 20 can provide energy for the ash vibrating mechanism 40 in the turnover process to store energy, and similarly, the ash vibrating mechanism 40 can also provide certain damping for the turnover mechanism 20, so as to facilitate the stable operation of the turnover mechanism 20.

As shown in fig. 5, the box body 10 further includes a trash can interface disposed at the bottom, an air inlet baffle 11 and an air outlet baffle 12 are disposed in the box body 10, the trash can interface is divided into a first vent and a second vent by the air inlet baffle 11, an air inlet channel and an air outlet channel are disposed in the box body 10, the air inlet channel is communicated with the air inlet 101 and the first vent, the air outlet channel is communicated with the air outlet 102 and the second vent 105, the turnover mechanism 20 is disposed in the air outlet channel, the air outlet baffle 12 extends inwards from the inner side wall of the air outlet channel and shields a part of the filter screen assembly 22 of the turnover mechanism 20 at the downstream side, and the other part of the filter screen assembly 22 of the turnover mechanism 20 shields the air duct between the second vent and the air outlet 102. Through setting up air inlet baffle 11, can separate the garbage bin interface, like this, take the air current of rubbish when passing through the garbage bin interface, most rubbish can all persist in the garbage bin, and only a small part of rubbish can cross air inlet baffle 11 and get into the air-out passageway, even these small part of rubbish enters into the air-out passageway, also can be blockked by tilting mechanism 20 to further avoid influencing the filter effect of dust removal case effectively.

Optionally, the air outlet baffle 12 is disposed at a side of the air outlet channel close to the air inlet baffle 11, and a bottom edge of the filter screen assembly 22 located at the bottom end is lower than a bottom edge of the air inlet baffle 11. Thereby further improving the filtering effect.

Particularly, air inlet baffle 11 extends along upper and lower direction, and air-out baffle 12 extends along the horizontal direction, and the upper end of air inlet baffle 11 links to each other with the one end of air-out baffle 12, and the air current is suitable for the lower extreme flow direction air-out baffle 12 that passes through air inlet baffle 11 from one side of air inlet baffle 11 to upwards lead to air outlet 102 through the other end of air-out baffle 12, pivot subassembly 21 locates the accommodation space of constructing between air inlet baffle 11 and the air-out baffle 12. So that the air flow can flow from the lower part of one side of the turnover mechanism 20 to the upper part of the other side, and the garbage on the filter screen assembly 22 can be cleaned conveniently, so that the filter screen assembly 22 can be recycled.

For example, the upper end of the air inlet baffle 11 is connected to the left end of the air outlet baffle 12, the airflow is suitable for passing through the lower end of the air inlet baffle 11 and the right end of the air outlet baffle 12 from the left side of the air inlet baffle 11 and upwards passing through the air outlet 102, and the rotating shaft assembly 21 is disposed in the accommodating space formed between the air inlet baffle 11 and the air outlet baffle 12. Of course, the air outlet baffle 12 can also be connected to the left side of the air inlet baffle 11, and the air is introduced from the right side to form the airflow flowing from the lower right to the upper left of the turnover mechanism 20. The above description of the present invention is based on the drawings, and the present invention mainly takes the example of the upper end of the air inlet baffle 11 being connected to the left end of the air outlet baffle 12, but is not intended to limit the scope of the present invention.

The air inlet 101 may be disposed on the box body 10 opposite to the air inlet baffle 11 and located on a side of the air inlet baffle 11 away from the air outlet baffle 12. In addition, the outlet 102 may be disposed at the top of the box body 10. Specifically, as shown in fig. 5 to 8, when the fan is started, the wind force follows the principle of the shortest wind direction, and circulates along the wind path shown in fig. 5, and the airflow carrying the garbage enters from the leftmost wind inlet 101, bypasses the lower end of the wind inlet baffle 11 on the left side of the turnover mechanism 20, passes through the bottommost filter screen assembly 22 on the turnover mechanism 20, then passes upward through another filter screen assembly 22, then continues to pass upward through the right side of the wind outlet baffle 12, flows to the wind outlet 102, and is discharged from the top wind outlet 102 of the box body 10. When the garbage in the airflow carrying the garbage is brought into the above path for ventilation by wind power, the larger garbage is blocked by the air inlet baffle plate 11 at the left side of the turnover mechanism 20 and falls into the garbage can, and the light garbage such as leaves, paper scraps and the like basically moves along the shortest path of the wind direction due to the light weight of the garbage. After bypassing the lower end of the air intake baffle 11, the airflow is first sucked onto the mesh of the bottommost filter screen assembly 22 on the turnover mechanism 20 by the wind pressure, so as to gradually block the mesh. When the blockage is severe, the screen assembly 22 becomes impervious to wind, and the dust collection plate 222 acts to provide a greater resistance to the flow of air through the screen assembly 22, so that when the screen assembly 22 is blocked, the screen assembly 22 is forced by the wind, thereby driving the inversion assembly to rotate about the shaft assembly 21.

As shown in fig. 9, in some embodiments of the present invention, the filter screen assembly 22 includes a filter plate 221, a dust deposition plate 222, and a collection plate 223, the filter plate 221 is connected to the spindle assembly 21 and extends away from the spindle assembly 21; the dust collecting plate 222 is connected with the filter plate 221 and is far away from the rotating shaft assembly 21, that is, the dust collecting plate 222 is connected to one end, far away from the rotating shaft assembly 21, of the filter plate 221, a wrapping structure with an opening facing the windward side of the filter plate 221 is constructed between the dust collecting plate 222 and the filter plate 221, and after the garbage is gathered in the wrapping structure, even if the filter screen assembly 22 is turned over, the garbage cannot escape from the wrapping structure, so that secondary pollution is avoided. The collecting plate 223 is connected to the filter plate 221 and close to the rotation shaft assembly 21, that is, the collecting plate 223 is connected to an end of the filter plate 221 close to the rotation shaft assembly 21, a collecting space is configured between the collecting plate 223 and the filter plate 221, and the collecting plate 223 is opposite to the dust deposition plate 222 in a radial direction of the rotation shaft assembly 21. Wherein, the filter plate 221 can be used for filtering the airflow carrying the garbage from the air inlet 101 to the air outlet 102, after the airflow passes through, a part of the garbage is attached to the filter plate 221, when the garbage on the filter plate 221 is more, the thrust of the airflow to the filter plate 221 is increased, the turnover mechanism 20 is turned over, the garbage on the filter plate 221 falls onto the collecting plate 223 when losing the thrust of the airflow, and the dust-collecting plate 222 can block the garbage, so as to prevent the garbage from passing to the air outlet 102 along with the airflow again, when the filter screen assembly 22 rotates to the upper side of the rotating shaft assembly 21, the collecting assembly can collect the garbage, so as to prevent the garbage from directly falling from the filter screen assembly 22, and to facilitate the collection of the garbage.

As shown in FIG. 7, the entire canting mechanism 20 rotates counterclockwise about the hub and the blocked screen assembly 22 moves away from the current position. Before the screen assembly 22 with the debris moves to the position shown in figure 7 (the topmost position of the flipper 20), the debris is blocked by the dust panel 222 and prevented from escaping from the stowed configuration to the upper right. When the garbage truck moves to the top end and the state shown in fig. 7, the air outlet baffle 12 is arranged above the turnover mechanism 20, so that the garbage instantaneously loses wind pressure at the position, falls down and is collected by the collecting plate 223. At this time, the air inlet 101 of the dust removing box 100 has no obstacle. When garbage continuously enters the filter screen assembly 22 blocked below the above path, the turnover mechanism 20 obtains stronger power and is continuously pushed by wind to rotate, and obstacles blocked at the position of the air inlet 101 of the box body 10 are sequentially removed. When the tilting mechanism 20 continues to rotate to the state shown in fig. 8, the high-position vertical screen assembly 22 returns to the horizontal position, and the garbage is collected and accumulated on the side of the collecting plate 223 in preparation for the next garbage dumping operation.

Alternatively, as shown in fig. 9 to 12, a plurality of screen assemblies 22 in the present invention are uniformly spaced around the circumference of the rotating shaft assembly 21, wherein, as shown in fig. 9, the turnover mechanism 20 may have four identical screen assemblies 22, and the screen assemblies 22 are distributed at 90 ° intervals, and the connecting shaft 211 at the center of the turnover mechanism 20 may be fixed to the box body 10 by a bearing assembly. The collection plate 223 is fixed to the filter plate 221. Of course, the above structures are only some specific embodiments of the present invention, and do not limit the protection scope of the present invention. The turnover mechanism 20 may have various forms such as three, five or more, and the like, and the structures shown in fig. 10 and 11 also belong to the protection scope of the present invention. The construction of screen assembly 22 is not limited to the pleated form shown in fig. 9, and may have a variety of configurations, such as the form shown in fig. 12. The position of the turnover mechanism 20 and the structure of the box body 10 are not limited to the above description and illustration of the drawings, and may be other positions as shown in fig. 13. It is within the scope of the present invention that the air outlet baffle 12 is disposed above the turnover mechanism 20.

In the present invention, when the garbage is collected on the collecting plate 223, it is necessary to remove the garbage on the collecting plate 223, and therefore, the collecting plate 223 in the present invention is configured to be inclined with respect to the horizontal plane, that is, when the lowermost screen assembly 22 of the turnover mechanism 20 is rotated by about 180 ° or 270 ° until the garbage on the screen assembly 22 is collected on the collecting plate 223, the collecting plate 223 is disposed to be inclined downward in a direction parallel to the axis of the rotating shaft assembly 21, so as to facilitate the removal of the garbage on the collecting plate 223. In addition, other structures can be arranged in the garbage bin to realize dumping and cleaning of garbage.

As shown in fig. 9, 14 and 15, in some embodiments of the present invention, the rotation shaft assembly 21 includes a connection shaft 211, a plurality of screen rotation shafts 216 and a restoring member 213, the connection shaft 211 being connected to the box body 10 and rotatable about an axis of the connection shaft 211; the plurality of screen rotating shafts 216 are arranged around the circumference of the connecting shaft 211, the screen rotating shafts 216 are connected with the connecting shaft, the plurality of screen rotating shafts 216 are connected with the plurality of screen assemblies in a one-to-one correspondence manner, and each screen assembly is rotatable around an axis perpendicular to the connecting shaft 211. For example, the screen rotating shaft 216 is connected to the connecting shaft 211, each screen assembly 22 is connected to the corresponding screen rotating shaft 216, and the screen assembly 22 can rotate around the axis of the screen rotating shaft 216 corresponding thereto; the restoring member 213 is connected to the screen assembly 22 and the coupling shaft 211, respectively, to drive the screen assembly 22 in parallel with the coupling shaft 211. Wherein, the reset piece 213 can reset the screen assembly 22, and since the screen assembly 22 can rotate around the axis perpendicular to the connecting shaft 211, the inclination angle of the collecting plate 223 can be increased, and the collecting plate 223 can be caused to vibrate, thereby clearing the garbage on the collecting plate 223.

Specifically, as shown in fig. 14, a screen rotating shaft 216 is connected to the connecting shaft 211, and a fixed plate 214 and a rotating plate 212 are connected to the screen rotating shaft 216, wherein the fixed plate 214 is fixedly connected to the screen rotating shaft 216, and the rotating plate 212 is rotatably connected to the screen rotating shaft 216. Specifically, the pivot plate 212 has bearings therein, and the screen shaft 216 passes through the bearings in the pivot plate 212 such that the pivot plate 212 is rotatably coupled to the screen shaft 216. the screen assembly 22 may include a screen frame 22a, and the screen frame 22a is fixedly coupled to the pivot plate 212. The reset element 213 may comprise a spring, as shown in fig. 14, and the screen assembly 22 may rotate about the screen spindle 216. A pair of ears 215 are fixed to the diagonal of the mounting plate 214, the ears 215 being connected to one end of the spring, the other end of the spring being connected to the mesh grid of the screen assembly 22. The elastic coupling of the screen assembly 22 and the coupling shaft 211 is finally accomplished. When the screen assembly 22 is rotated by an external force, the rotating plate 212 and the fixed plate are driven to rotate relatively, and the spring is stretched. When the screen assembly 22 loses its external force, it is pulled back by the spring to return to its original horizontal position. The filter screen assembly 22 may include a screen frame, the filter screen is disposed on the screen frame to construct the filter screen assembly 22, and the screen frame is connected to the rotating plate 212.

Alternatively, as shown in fig. 16 to 19, the end of the screen assembly 22 away from the screen rotation shaft 216 is provided with a crashing flip 224, and the tank body 10 is provided with a crashing block 13 protruding toward the crashing flip 224, and the crashing flip 224 is adapted to collide with and pass over the crashing block 13 during rotation of the screen assembly 22 about the connection shaft 211 so that the screen assembly 22 can be overturned about the axis of the rotation plate 212 to dump the trash. When the impact turnover part 224 impacts and crosses over the impact mass 13 during the rotation of the turnover mechanism 20 around the rotation shaft assembly 21, the screen assembly 22 will vibrate, thereby achieving dust removal.

Specifically, fig. 17 is a schematic view showing the tilting mechanism 20 engaged with the impact mass 13.

The ash-shaking rotating shaft 41 penetrates into the accumulator housing 52.

The concrete structure of the ash shaking process and the ash shaking mechanism of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 23 to 25, a set of link devices is provided inside the box body 10, and the dust vibrating mechanism is powered by the rotation of the garbage turning mechanism 20. The turnover mechanism 20 and the ash vibrating rotating shaft 41 can be connected through belt transmission, and in combination with the foregoing embodiment, the rotating shaft assembly 21 is fixed with the driving wheel 45a, the driving wheel 45a winds the belt 45d and transmits the belt to the driven wheel 45b, the driven wheel 45b is fixed with the ash vibrating rotating shaft 41, and when the driving wheel 45a rotates, the belt is transmitted to the ash vibrating rotating shaft 41 to synchronously rotate. So as to realize the transmission connection between the turnover mechanism 20 and the energy storage mechanism 50.

In addition, the driven wheel may be connected to one end of the dust vibration rotating shaft 41, and the synchronizing wheel 45c may be fixed to the other end of the dust vibration rotating shaft 41, and the diameters of the synchronizing wheel 45c may be the same (or different) as those of the driven wheels 45 b. Alternatively, as shown in fig. 25, one end of the ash vibration rotating shaft 41 may be supported by a fisheye bearing 46, the fisheye bearing 46 may be fixed to the tank body 10 by a bearing seat, and the other end of the ash vibration rotating shaft 41 may be fixed to the tank body 10 by an energy storage mechanism 50, so that the ash vibration rotating shaft 41 may be rotatably supported on the tank body 10. Wherein the energy storage mechanism 50 and the fisheye bearing 46 may be connected to the top wall of the tank body 10.

When the ash vibration rotating shaft 41 rotates clockwise, the spring 53 wound on the shaft starts to wind up for energy storage. As shown in fig. 27, in the structure of the spring 53, the spring 53 is characterized in that the energy is accumulated in a winding manner and the number of reeds wound on the inner side is gradually increased. When the energy storage reaches a certain level, the overall diameter of the spring 53 begins to decrease at this point. The ratchet tooth surfaces of accumulator housing 52 remain in contact until the spring 53 does not begin to diminish. When the ash shaking rotating shaft 41 continuously rotates clockwise to give torque to the spring 53, the accumulator starts to accumulate energy. When the ash vibration rotating shaft 41 loses the support of the input torque, the tail end of the spring 53 is clamped at the tooth root of the ratchet wheel to generate a support reaction force. At this time, the spring 53 returns to its original shape to rotate the ash-vibrating rotating shaft 41 counterclockwise. The driven wheel 45b then also starts to rotate counterclockwise. If the critical point at which the outer diameter of the spring 53 begins to decrease is exceeded when torque is continuously applied to the ash-shaking rotating shaft 41, the maximum diameter of the spring 53 begins to decrease, the friction force decreases, and the spring surface loses radial pressure on the ratchet wheel on the inner circumference of the accumulator housing 52. Therefore, the outermost winding of the spring 53 is carried by the ash-vibrating shaft 41 to continue counterclockwise, and the tail end of the spring 53 slides along the slope of the ratchet teeth and moves along the inner winding of the accumulator housing 52. The produced effect can prevent the whole mechanism from being completely locked, and the protection structure is an energy storage overload protection structure. The energy storage capacity is completely determined by the number of turns of the spring 53, and the more the number of turns, the stronger the energy storage capacity.

As shown in fig. 25, the linkage 42 may include a first link 421 and a second link 422, one end of the first link 421 is eccentrically connected to the ash vibrating rotating shaft 41 and is adapted to be driven to rotate by the ash vibrating rotating shaft 41, the other end of the first link 421 is rotatably connected to one end of the second link 422, the second link 422 is movably disposed on the box body 10 in the up-down direction, and the other end of the second link 422 is connected to the ash vibrating member 43. Wherein, both ends of the ash-vibrating rotating shaft 41 are connected with the connecting rod group 42, and both ends of the ash-vibrating piece 43 are connected with the connecting rod group 42 respectively.

Specifically, one end of the first link 421 in the two link groups 42 is respectively installed on the driven wheel 45b and the synchronizing wheel 45c, the installation point is in the area deviated from the center of circle, the middle parts of the second links 422 on both sides respectively penetrate through the link blocks fixed on the box body 10, and the second links 422 are movably matched with the link blocks along the up-down direction. When the ash vibrating rotating shaft 41 rotates, the driven wheel 45b and the synchronizing wheel 45c also rotate, and the mounting point above the first connecting rod 421 eccentrically rotates around the center of a circle, so as to drive the second connecting rod 422 to reciprocate up and down in the connecting rod block, thereby forming a crank linear motion mechanism, and schematic diagrams are shown in fig. 28 and 29. The lower end of the second connecting rod 422 is connected with the ash vibrating piece 43, and the ash vibrating piece 43 is vertically connected with the second connecting rod 422. The lower end of the flexible filter element 30 is magnetically attracted with the dust vibrating element 43. Wherein the dust vibrating member 43 may be provided as a magnetic rod, and the lower end of the flexible filter member 30 may be provided with an iron rod. When the lower end of the second connecting rod 422 reciprocates up and down, the magnetic rod adsorbs the iron rod to reciprocate up and down. The flexible filter member 30 is repeatedly in a tensioned and relaxed state by its own elastic deformation. In addition, the flexible filter member 30 may be a dust removal cloth bag, and an iron rod is connected below each cloth bag of the dust removal cloth bag, the plurality of iron rods are arranged along the extending direction of the dust vibration member 43, and the plurality of iron rods are magnetically attracted to the magnetic rods, and due to the magnetic force, the iron rods are attracted to and attached to the magnetic rods.

In combination with the above, the ash vibration rotating shaft 41 is connected with a rocker 44, the rocker 44 can be connected to the position of the outer side of the synchronizing wheel 45c deviating from the center of the circle, the synchronizing wheel 45c can be manually driven to rotate through the rocker 44, and the above mechanisms can also be operated. Of course, the synchronizing wheel 45c may be driven to rotate by other electric or pneumatic means.

As shown in fig. 28, in the energy storage stage, wind indicated by an arrow enters from the air inlet 101 to push the turnover mechanism 20 to rotate clockwise, at this time, the driving wheel 45a and the driven wheel 45b rotate clockwise together, the driven wheel 45b drives the ash vibrating rotating shaft 41 to rotate, and the energy storage mechanism 50 starts to store energy as in the previous process.

As shown in fig. 29, when the work is stopped and the wind is lost, the torsion of the torsion spring 53 in the energy storage mechanism 50 is lost, and the driven wheel 45b starts to rotate reversely while the vibration ash rotating shaft 41 rotates counterclockwise. The linkage 42 starts to reciprocate up and down to drive the magnetic bar to adsorb the iron bar to reciprocate up and down. The cloth bag which is full of dust shakes off the dust in a loose and tight relaxation state, and the dust shaking and cleaning work is completed. When the reverse torque is too large, the link mechanism moves up and down too strongly, the magnetic attraction structure can be designed to disconnect the magnetic rod from the iron rod under the condition of too large pulling force, and the mechanism is prevented from being blocked to generate severe impact.

If the cleaning environment does not have enough garbage to block the garbage turnover mechanism 20, the collecting plate 223 in the mechanism can also play a role of being reversely pushed by wind power due to a certain wind shielding area, and the above movement can still be carried out. And after the air source stops after each operation, the automatic dust vibration action can be carried out. Dust accumulation can be effectively prevented, and excessive manual cleaning is not needed.

If further shaking of the ash is required after the ash shaking finishing mechanism is stopped, the rocker lever 44 can be manually rotated to allow the mechanism to be operated again, and the ash shaking time is artificially increased.

The energy storage mechanism can be used for storing energy when the garbage turnover device rotates to work in the operation process, the releasing capacity is used for vibrating ash, the power source device is reduced, and the cost is saved. The unique operation mode of the dust vibration box can enable the box body 10 to automatically perform the dust vibration action once after each operation is finished, and the situations that workers forget to clean dust for a long time and the dust is difficult to clean in the later period are prevented. Through utilizing the replacement of sack relaxation state to shake the ash, the effect is better, and shakes the ash process and can not produce the noise like ordinary vibrating motor ash scheme that shakes. The structural design of sack below magnetism absorption can effectively protect the violent impact that causes when transshipping, prevents that the mechanism from damaging.

With the above embodiments, in the dust removing mechanism of the present invention, after the garbage is collected by the unique structure of the filter screen assembly 22, the garbage can be effectively prevented from escaping due to the design of the packing structure. Effectively blocking the garbage from flying into the interior of the box body 10. Compared with the current situation that the traditional fixed filter screen plate can only filter but cannot prevent blockage, the garbage turnover device can continuously transfer garbage, and effectively prevents the garbage from being blocked at the air inlet 101 of the box body 10. The turnover mechanism 20 composed of a plurality of filter screen assemblies 22 can not only form a multi-layer blocking effect on light floating garbage, but also improve the transfer efficiency of blocking garbage. The movement of the turnover mechanism 20 does not need to add an additional power source, and the mechanism can operate to transfer garbage as long as the dust-absorbing wind source continues. The discharge box 14 may provide a transport path for the dumped refuse, preventing the refuse from being rewound back into the wind tunnel. The wind energy is effectively utilized, the energy can be stored for the ash vibrating mechanism in the operation process, the stored energy is utilized to vibrate the ash, the power source device is reduced, and the cost is saved. Unique operation mode can let case body 10 once shake grey action automatically after the operation is ended every time, prevents that the staff from forgetting, causes the dust to be long-term long-pending, the more and more difficult condition of clearing up in later stage. Through utilizing the replacement of sack relaxation state to shake the ash, the effect is better, and shake the ash process and can not produce the noise like ordinary vibrating motor shakes the ash. The structural design of sack below magnetism absorption can effectively protect the violent impact that causes when transshipping, prevents that the mechanism from damaging.

In addition, after cleaning or in the cleaning process, the flexible filter member can be vibrated to prolong the single use time of the sanitation equipment and avoid the problem that the final cleaning is difficult because a user forgets to clean the flexible filter member in time.
